SPECIFICATION forming part of Letters Patent No. 496,140, dated April25, 1893.

Application filed September 10, 1892- Serial No. 445,516. (No model.)

To all whom it may concern.-

Be it known that I, ISAAC SEXTON, of Somerville, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvementsin Can-J ackets, of which the following is aspecification.

This invention relates to sheet-metal jackets used to inclosecylindrical sheet-metal cans, to protect the bodies of the cans frominjury.

The invention consists in the hereinafter described improvements intheforrn and construction of the upper end or portion of the can jacket,whereby the construction is made cheap and simple and a strong andeffective jacket is produced.

In the accompanying drawings forming part of this specification, Figure1 represents aside elevation of a sheet metal can and a sectionalelevation of a jacket thereon, provided with my improvements. Fig. 2represents a similar jacket showing a modification. Figs. 3, 4:,

and 5 represent sectional views of a portion of the jacket, showing thesteps employed in forming the same. Fig. 6 represents a modification.

The same letters of reference representthe same parts in all thefigures.

In the drawingsa represents a sheet-metal can of the usual form, and 1)represents a sheet-metal jacket formed to cover all portions of the canbelow the breast a thereof, the jacket being of sheet-metal and providedwith a suitable bottom, on which the bottom of the can a rests.

In carrying out my invention I make the jacket I) of sheet metal, andprovide it at its upper end with a sheet 8 which projects inwardly fromthe inner surface of the jacket, and is adapted to bear on the body ofthe can, and thus prevent contact between the jacket and the body of thecan. I also provide the jacket with an outwardly projecting flange b,adapted to support the lip a at the base of the breast a, the saidflange and the seat 8 being integral with the jacket and formed bysuitably bending the sheet metal that constitutes the jacket. I preferto form the upper portion of the jacket into a double,outwardly-projecting flange b, by doubling over the metal of the jacketas indicated in Fig. 3, the

doubled over portion being turned inwardly against the inside of thejacket, and then bending a part of said doubled portion outwardly asshown in Fig. 4, a part of the doubled over portion remaining in contactwith the inner surface of the jacket below the flange, and constitutingthe inwardly projecting seat 8. I thus provide the jacket with anoutwardly-projecting flange, the upper portion of which is substantiallyhorizontal and constitutes a seat or bearing for the lip a at the baseof the breast of the can, and With an inwardly projecting seat .5, boththe seat and flange being integral with the body of the can. By doublingthe upper portion of the jacket as described I not only increase itsstrength but also separate the inner surface of the jacket from theouter surface of the body of the can, thus forming an air space betweenthe can and the jacket, so that indentations formed in the jacket bycontact with external objects will not be formed in. the body of thecan; hence the can can be readily removed from the jacket whenever suchremoval is desirable; whereas, if the body of the can were in contactwith the jacket, both the body of the can and the jacket would beindented together, so that it would be difficult or impossible to removethe can from the jacket.

In Figs. 1 and 5 Ishow the upper end of the jacket curved inwardly orcontracted to increase the inward projection of the seat 3 and thusincrease the width of the annular space between the can and jacket.

In Fig. 6 I show the seat 3 formed wholly by the inward curvature orcontraction of the upper portion of the jacket, only the flange beingdoubled.

It will be seen that by providing the jacket with an inwardly projectingseat to bear on the can body and with an outwardly projecting'fiange tosupport the lip of the can, said seat and flange being integral with thejacket and formed by bending the material thereof, I increase theefficiency of the jacket without adding to its cost.

I claim- 1. A sheet metal can jacket, having at its upper end a seatprojecting inwardly from its inner surface to bear against the body ofthe can and form an annular space between the bear on the can body and pve contact can and jacket, and a doubled outwardly protween the mainportion of the jacket and the jecting flange to support the lip at thebase can therein, as set 'forth. 15 0f the breast of the can, said seatand flange In testimony whereof I have signed my name 5 being integralwith the jacket and formed by to this specification, in the presence oftwo bending the material thereof, as set forth. subscribing Witnesses,this 5th day of Septem- 2.
